If you want to back up your Figma designs automatically to independent formats to avoid vendor lock-in, Magicul is worth a look. Magicul is a design-to-anything converter engine that also can convert files from Adobe XD, Sketch, Photoshop, Illustrator and PDF. It includes features like automatic Figma design backup to independent formats, an online inspector to view and edit design files, and preservation of text and color styles. It can help you streamline your design process and save time on conversions, so it's good for small and large teams, including freelancers and Fortune 500 companies.
Another option is data.to.design, which directly integrates with Figma to fill designs with real data from a variety of sources like .CSV files, Notion, Airtable, JSON files and Google Sheets. That can help you build more realistic prototypes and speed up your design process. It's geared toward bringing real data into your designs, but it also has tools to handle different data formats, so it's a good option for designers who want to build more impactful products with more realistic user experiences.
